LOCK. v .s

-SPECIFICATION forming part of Letters Patent N o. 746,174, dated December 8, 1903.

Application filed July 17, 1903.

. Lock,of which the following is a specification.

. My invention relates to keyless locks; and the objects of my improvement are to construct a lock that shall be simple and strong, that cannot be opened except by a person familiar with its operation, one in which the reciprocating bolt is automaticallysecured in either locked orV withdrawn position and which, if desiredmay have an auxiliary bolt that may be operated together with or `independent of the main bolt. I attain these objects by the construction illustrated in the accompanying drawings, in which- K Figure 1 is a view of the mechanism with the bolts in locking position, one side of the casing being removed. Fig. 2 is a view of the same in the unlocked position. Fig. 3 is a horizontal cross-section through the shaft, and Fig. 4 shows a padlock constructed with my improved mechanism. 4

Similar reference characters refer to like parts throughout the specification.

Through the case 1 ofv the usual form eX- tends the square shaft 2, to the ends of which are secured the knobs 3. Loose on this shaft are the sleeves 4, havingY knobs 5. Fast on the shaft is mounted the releasing and locking collar, having a lug 6, which engages in a notch in the bolt 7 to withdraw or shoot the same. On one sideof lug 6 is the tumbler 8, loose on the shaft, provided with a groove 9, into which fit lugs on the end of one of the sleeves 4. On the other side of lug 6 is asecond tumbler 10, which is also loose on the shaft and is provided with a similar groove to be engaged with lugs on the other sleeve. This tumbler 10 has arms 30, that project around lug 6 without contacting and enter openings 3l and 32 inthe tumblerrS. The two sleeves 4 and the two tumblers will therefore turn together. Mounted on the pin 11 is the bar 12, which is provided with two notches and which is partly cut away on the sides. The upper end rests against the head of thebolt 7. The tumbler 8 is provided with an arm 13, a lug 14, and a second notched arm 15. Guides 16, attached tothe case, hold the Serial No. 165,965. (No model.)

slidable bolt 17 in place. A spring 18 presses bolt 17 upward. When the bolt 17 is in the locked position, as shown in Fig. 1, the bar 12 is held by the arm 13 and lug 6. The bolt 17 is held up behind a shoulder of the bolt 7. When the bolt isto be withdrawn, a knob 5 is turned to .the right, lifting arm 13 out of its notch vin bar 12 and depressing bolt 17. A knob 3 is then turned, which causes lug 6 to engage in the tapering notch in thebolt 7, withdrawing the said bolt. If tumbler 8 is turned too far, the lug` 14 will assume the dotted position in Fig. 1 and prevent bar 12 from moving rearward. Upon the Yrelease of knob 5 the spring 18 will press the bolt 17 into notch 19, thus locking bolt 7 in the withdrawn position. To shoot the bolt, a knob 5 must first be turned backa distance suflicient to disengage bolt 17 from the notch 19, when turning a knob 3 to the left will shoot the bolt.

An auxiliary bolt 20, moved by the lug 21, fast on a collar on shaft 22, maybe provided. This shaft has knobs 23. The spring 24 keeps this bolt 2OV in the forward position. This part of the lock maybe usedl while the bolt 7 is held locked in its withdrawn posi-tion. It will be observed that bolt 7 must be withdrawn before the operation of the knobs 23 will avail. V

Fig. 4 shows a padlock with my improvel ment. The bolt 25 has'no notch 19, as vthe construction is that of thewell-known springlock. The bar 26 under the influence of spring 27 constantly tends to throw the bolt 25 to the left. The method of lunlocking is the same as in thedooilock shown.

Having now explained my improvement, what I claim as my invention, and desire to secure by Letters Patent, is-

1. In a lock, the combination of the case, a locking-bolt slidable therein, a hinged bar for holding said bolt in the locking position, a pivoted tumblerengaging said bar, a shaft with knobs on both ends to rock said tuin- IOO arms engaging openings in the other tumbler so that the sleeves and tuinblers Will revolve together, said tuinblers controlling the actuation of the locking-bolt.

In a lock, the combination of the case, a locking-bolt slidable therein, a shaft passing through said case, knobs on the ends of said shaft, means fast on said shaft to aotuate said bolt, sleeves on said shaft, a hinged bar to hold said bolt in its locking' position, and means attached to said sleeves to hold said hinged bar in position to secure the lockingbolt.

4. In a lock, the combination of the case, a locking-bolt slidable therein, a slidable bar to hold said bolt in the locking,l and Withdrawn positions, a shaft, a collar on said shaft having a lug,l for actuating said locking-bolt, a pivoted bar controlling` the operation of the locking-bolt, and means supported by said shaft for engaging the pivoted bar and for actuating1 the slidable bar to release the looking-bolt.

5. In a lock, the combination of the ease, a locking-bolt slidable therein7 a shaft passing through the casing, a collar fast on ,said shaft havingalug to aetuate the bolt, a pivoted bar havingl a notch, a slidable bar for locking' the bolt in the advanced and Withdrawn positions, a spring attached at one end to the pivot of the pivoted bar and serving to press the slidable bar toward the locking-bolt, and means loose on the shaft to slide said bar and having` an arm to engage in said notch and lock said pivoted bar.

6, In a lock, the combination of the case, a lockingbolt slidable therein, a shaft passing' through said case, knobs on the ends oi' said shaft, means fast on said shaft to actuate said bolt, sleeves on said shaft, a hinged bar to hold said bolt in its locking position, means attached to said sleeves to hold said hinged bar in position to secure the locking-bolt, an auxiliary bolt in said case, and means for operating,l said auxiliary bolt.

In testimony whereof I have signed my name in the presence of two subscribing Witnesses.

JACOB SGIIELL.
